Submit 2 Fitness, Secaucus

Working out should never be boring. That's the idea behind Submit 2 Fitness, a center that trades machines for challenging group classes. Here, members boost their endurance and shed pounds in motivating programs such as spinning, cross training, and Warrior Camp, which blends high-energy cardio exercises with strength training and interval training. Classes are led by instructors who each boast expertise in their particular field.
